In this study, a novel active disturbance attenuation controller is investigated for the permanent magnet synchronous motor servo system by integrating a feedback domination technique and disturbance observer‐based control strategy. A disturbance observer is first constructed to enable an active estimation process of the mismatched disturbances. Second, the authors adopt a feedback domination technique, rather than popularly used feedback linearisation methods, to handle the system non‐linearities. A Lyapunov function‐based recursive design is then carried out to derive the composite controllers in an explicit way, while a semi‐global input‐to‐state stability can be guaranteed. The proposed methodology not only performs an improved closed‐loop control performance comparing to several existing results, but also renders a simple control law which will ease its practical implementations. Abundant comparison simulation results are provided to demonstrate the effectiveness of the proposed scheme.
